We are aware that weight is the product of applied gravitational force and mass. W = MG thus, where W represents the weight, M the mass, and G the gravitational force. As a result, it might also mean that "an object's weight is directly proportionate to its mass."
<h3>What is mass?</h3>
- Mass is a physical body's total amount of matter.
- It also serves as a gauge for the body's inertia, or resistance to acceleration (change in velocity) in the presence of a net force.
- The strength of an object's gravitational pull to other bodies is also influenced by its mass.
- The kilogram is the primary mass unit in the SI (kg).
- Even though weight is frequently measured using a spring scale rather than a balancing scale and directly compared with known masses, mass is not the same as weight in physics.
<h3>What is weight?</h3>
- The force exerted on an object by gravity is known as the weight of the object in science and engineering.
- Weight is sometimes described as a vector quantity, or the gravitational force exerted on the object, in some common textbooks.
- Others define weight as a scalar quantity, the gravitational force's strength.
- Others define it as the strength of the force applied to a body as a result of systems designed to resist the effects of gravity; the weight is the amount that is determined, for instance, by a spring scale.
